Special Issue Information

Dear Colleagues,

Biomedical optical imaging is a rapidly developing field with numerous exciting applications in clinical diagnosis and biological research, which is due to the superior spatial resolution, rich imaging contrast, and non-ionizing properties of light radiation. Important new advancements of optical imaging equipment and technology can contribute to key breakthroughs and discoveries in disease diagnosis and biological exploration, such as photoacoustic imaging, optical coherence tomography, diffuse optical tomography, fluorescence spectroscopy, Raman spectroscopy, confocal and multiphoton microscopy, super-resolution microscopy, and many others. Some technologies have been translated to biomedical applications, and some are yet to be applied. Joint efforts from both the optical and biomedical communities are still needed to fully discover the potential of these optical modalities and promote them as routine laboratory and/or clinical apparatuses.

This Special Issue invites manuscripts that introduce recent advances in “Advanced Techniques in Biomedical Optical Imaging”. All theoretical, numerical, and experimental papers are accepted for submission. Original research papers and review articles are both welcome. Topics include, but are not limited to, the following:

  • Optical microscopy;
  • Photoacoustic imaging and spectroscopy;
  • Optical coherent tomography;
  • Diffuse optical tomography;
  • Spectroscopic and imaging techniques;
  • Multimodality and multiscale approaches;
  • Machine learning and image processing;
  • Basic research and translational research.

Digital holography (DH) is a novel, real-time, non-destructive, and quantitative phase-contrast imaging method that is particularly suitable for label-free live biological cell imaging and real-time dynamic monitoring. It is currently a research hotspot in the interdisciplinary field of optics and biomedical sciences, both domestically and internationally. This article proposes an improved angle spectrum algorithm based on holographic technology, which reconstructs a cellular hologram based on phase information. Optical images and chromosome cell images, reconstructed using holographic technology at different diffraction distances under the improved angle spectrum algorithm, were analyzed and compared. The optimal diffraction distance for reconstructing chromosome cell images was selected, and chromosome cell images reproduced using traditional angle spectrum algorithms, angle spectrum algorithms combined with GS, and improved angle spectrum algorithms were compared. Comparative experiments with the different models show that the proposed algorithm is superior to traditional angle spectrum algorithms in reconstructing cell images based on phase information. Furthermore, experiments have shown that images reconstructed using the improved algorithm can resolve high signal-to-noise ratio information. This algorithmic improvement provides new applications for cellular detection in clinical diagnostics and is more suitable for cell phase reconstruction in practical applications. Full article

Compared with optical coherence tomography (OCT) in the near-infrared domain, the visible-light OCT (vis-OCT) system affords a higher axial resolution for discerning subtle pathological changes associated with early diseases. However, the significant material dispersion at the visible-light range leads to a severe problem for dispersion management in vis-OCT systems, which results in a compromised axial resolution. While dispersion compensators (such as prism pairs) are commonly used, a digital method is still highly desirable and has been widely used to compensate for the residual dispersion imbalance between the reference and sample arms in an OCT system. In this paper, we develop a generic approach to effectively compensate for the system dispersion, especially the higher-order dispersion in the vis-OCT system, by using a single arbitrary measurement of the mirror-reflection (SAMMR) method and its resulting phase information. Compared with the previous methods, including the method based on the Taylor series iterative fitting and differential method, the proposed method does not need to extract the dispersion coefficients or use the metric functions and affords a better performance for axial resolution and the signal-to-noise ratio in vis-OCT systems. Its effectiveness is further validated in an OCT system operating in the near-infrared domain. Full article

The refractive index (RI) is one of the liquid’s most important physical parameters of liquid. The change of RI usually indicates the change of liquid properties, and this relation leads to broad application. This paper proposes a method based on optical coherence tomography (OCT) to measure the RI of liquid in real time. A series of targeted image-processing techniques play a vital role in this method. Benefiting from the advantages of OCT, this method does not require the operators to come into direct contact with liquids. Moreover, the principles and techniques adopted in this method imply that the measuring range of RI of unknown liquids is unlimited. The effectiveness of this method is validated by the experiment measuring the RI of sucrose liquids with gradient concentration. Another experiment thoroughly verifies this method’s feasibility in predicting sucrose concentration based on real-time measured RI. This simple and easy proposed method indicates an immense potential application prospect in the industry and scientific research. Full article
